The virus is currently affecting 10 countries worldwide and endemic in three including Pakistan.

The WHO has urged infected nations to implement vaccine requirements for all international travel.

"Special measures will include establishing mandatory immunisation counters on all airports, border crossings and seaports for all travellers," Pakistani government spokesman, Sajid Ali Shah, said.

State minister for Health Sciences Regulation and Coordination, Saira Afzal Tarar, said officials had yet to work out the details of when and how the policy would be implemented.

"Passengers travelling abroad now should not worry about it," she said.

Ms Tarar said the government would hold a meeting on Wednesday with provincial ministers and health officials to discuss the vaccination program.

Playing into Taliban's hands

The Taliban and other militants violently oppose polio vaccination campaigns, seeing them as a cover for foreign spying, and regularly attack immunisation teams.

Ms Tarar has accused the WHO of playing into the Taliban's hands, saying the health body's recommendations has isolated Pakistan and would make life harder for ordinary Pakistanis, thereby helping the militants achieve their goals.

"By recommending travel restrictions on Pakistan, the WHO has strengthened those forces who actually banned polio drops," she said.

Militants have killed around 56 people during vaccination campaigns since December 2012.

Their opposition to immunisation has increased since Pakistani doctor Shakil Afridi helped the CIA track down Osama bin Laden in 2011 through a fake vaccine project.

Ms Tarar has blamed the surge of cases in Pakistan mainly on "a reaction to the Afridi case".

Widespread public fears that the vaccine leads to infertility have also contributed to a re-emergence of the disease in Pakistan.

Surge in cases

Pakistan recorded 91 cases of polio last year, according to the WHO, up from 58 in 2012.

It has also recorded 59 of the world's 74 cases so far this year.

The WHO called on Pakistan, Cameroon and Syria, countries seen as posing the greatest risk of exporting wild poliovirus, to ensure all residents and long-term visitors receive a polio vaccine between four weeks and a year before travelling abroad.

For urgent travel, at least one vaccine dose should be given before departure, according to the emergency committee, which also called for all travellers to be given certificates proving they have been immunised.

Mr Shah said it had not yet been decided whether long-term non-Pakistani residents would also be subjected to the new rules.

Last month officials announced they would begin administering polio drops to children at security checkpoints in the country's lawless tribal belt.

Health authorities had come close to beating the disease as the result of a 25-year-long effort, with the number of recorded cases worldwide plunging from 350,000 in 1988 to 417 in 2013.
